We stopped at Long Branch and caught the GO train back to Burlington. We were already at 100 km for the day, so to close the circle back to Burlington would have been another 30 km
So, I am not sure if the kms listed (173) is entirely accurate but in total for us with starting from Burlington and visiting Acton our two day ride would have been 210km.
We would totally recommend a detour to Acton before heading to Georgetown on Day One and then possibly an extra day to ride along the Caledon Trail with maybe an overnight in Brampton. You could then enjoy a day on the Etobicoke Creek continuing to Long Branch or Port Credit or even Burlington (or Toronto if you want to head the other direction of course.) We feel that this would extend the appeal to cyclists with varying skill and drive.
Had a great time. Would do day 2 again and really appreciated learning about these “new to us” trails!
